We'll help you confirm the right combination for your engine.

Stage 1 Performance

A strong starting point.

Stage 1 ECU remapping is generally designed for compatible vehicles using standard engine hardware.

It's a popular option for drivers looking for stronger acceleration, additional usable torque and improved engine response without moving directly into a major hardware build.

Included

  • Stage 1 ECU software, subject to vehicle compatibility and the actual quoted service

Optional extras

  • + Compatible gearbox tuning
  • + Approved performance intake
  • + Other suitable supporting upgrades

Vehicle-specific price

ECU & Gearbox Package

Engine and transmission software together.

On suitable automatic cars, engine ECU remapping and gearbox TCU tuning can be considered together.

The engine and gearbox control different parts of the driving experience, so it's important to check compatibility rather than assume every automatic vehicle needs both services.

Included

  • Engine ECU remapping (Stage 1 or other approved option)
  • Gearbox / TCU tuning, only where the exact transmission is supported

Optional extras

  • + Suitable intake
  • + Stage 2 planning
  • + Relevant supporting components

Stage 2 Performance Package

Software planned around supporting hardware.

Stage 2 ECU tuning is considered for compatible engines with suitable supporting performance components.

The required parts vary between vehicles. Depending on the engine, an intake, intercooler or other appropriate hardware may need to be considered before the correct software can be confirmed.

Included

  • Stage 2 ECU software, subject to verified compatibility
  • Supporting hardware selected for the actual engine and setup
  • Installation, quoted where applicable

Custom Tuning Package

For modified cars and individual requirements.

Already fitted performance parts or planning a more involved build?

Custom tuning enquiries are suitable for customers who need individual advice about their engine, existing modifications, supporting hardware and software options. Tell us what you're running and what you're hoping to achieve.

Possible enquiries

  • + Existing intake or intercooler
  • + Hybrid or upgraded turbocharger
  • + Existing ECU remap
  • + Gearbox tuning
  • + Individual calibration requirements

Package availability depends on the exact vehicle. Images are illustrative. Stage 2 never automatically includes a downpipe or emissions-system modification.

See the available performance figures for your car.

Before choosing a tuning package, it's useful to understand what's available for your engine.

STX Tuning lists vehicle-specific power and torque estimates for supported engines, helping customers compare standard figures with available Stage 1 and Stage 2 tuning options.

The figures are estimates for the listed engine specification, not guaranteed measured results for your individual vehicle.

Standard stage figures are not a guaranteed output for a custom combination of components.

Choose your vehicle to see its figures

Only verified catalogue values are shown. No figures are estimated for hardware combinations.

Automatic gearbox and transmission components, illustrative image

ECU & gearbox tuning — working together where suitable.

Engine ECU remapping and gearbox TCU tuning are separate services that affect different parts of your car.

An ECU remap changes supported engine software settings and may increase the power and torque available.

Gearbox software, where supported, can change certain transmission behaviours such as shift response or torque management.

On some automatic vehicles, reviewing both systems together can make sense, particularly where engine torque is being increased.

However, gearbox tuning isn't automatically required on every remapped car, and the right combination depends on the actual transmission.

Check the gearbox before adding a TCU remap.

Not every transmission supports the same software options, and mechanical limits still apply.

Go beyond ECU software with the right hardware.

Some customers start with a Stage 1 remap. Others already have performance modifications or are planning a more involved build.

Suitable hardware can form part of a performance package, but the correct components depend on the engine and intended setup.

Performance air intakes & induction

Explore suitable intake and induction components for compatible engines.

The effect of an upgrade depends on the original intake design, engine and overall setup.

View intake upgrades

Performance intercoolers

On suitable turbocharged engines, charge-air cooling may be an important consideration when reviewing a higher-performance setup.

An upgraded intercooler isn't automatically required for every vehicle.

View intercooler upgrades

Performance exhaust systems

Ask about compatible exhaust components, sound characteristics and suitable workshop fitting.

Any modifications must be appropriate for the vehicle's intended use and applicable requirements.

View exhaust upgrades

Turbo & hybrid turbo options

Considering a higher-output performance build?

Turbocharger changes may require additional supporting components and a suitable custom ECU calibration. Compatibility, costs and expected results must be checked for the exact engine.

Explore custom tuning

Images are illustrative. Catalytic-converter, DPF or other emissions-control removal is never included as a performance upgrade.

Know exactly what you're asking us to quote.

A tuning package should be clear about the work being proposed.

An ECU remap, gearbox software, performance part and workshop fitting are not interchangeable services.

At STX Tuning, your quotation should identify the relevant work so you can understand what is included and which additional options are being considered.

Included where quoted

  • Selected ECU software

    The Stage 1, Stage 2, economy or custom software service specified in your quotation.

  • Selected gearbox software

    Only where supported and explicitly included.

  • Selected hardware

    Only the compatible parts actually agreed in the quotation.

  • Fitting & related work

    Included only where clearly specified.

Not automatically included: dyno runs, warranties, fitting or extra parts unless your quotation confirms them.

No hidden assumptions. Know the scope of work before you agree.

How much does a car tuning package cost?

The price of a tuning package depends on the vehicle, ECU, selected software services and any supporting hardware or installation work required.

A Stage 1 ECU remap may have a verified price in our vehicle catalogue. A package combining ECU software, gearbox tuning and performance parts needs to account for the individual services and their compatibility.

That's why we let you build your package before asking STX Tuning to confirm the complete quotation. Choose your vehicle, select your options and send us the summary.

    I wanted to leave a genuine review, I got my car remapped on the 5th June 2026. Making the appointment was very easy, I didn’t have to wait too long for an appointment and had the option for someone to come to my house if needed. The remap was done within an hour or so. My light did come back on a week after the remap was done, but I was able to clear it with no issues and last weekend I took a 4 hour round trip to the beach and the light did not come back on when usually it does after about 1hr into a drive. The point of my long review is I highly recommend this company and I am very happy with the service provided.
